To all whom may concern: i

Be it known that I, JOSHUA J. Amman,

a citizen of the United States residing at Pinemount, in the county of uwanee and mit of the replacing of a broken spoke, or p for any other purpose, and which, when assembled, holds the inner ends of the spokes l5 tightly clamped between two of its members, and at the same time forces the spokes out against the felly of the wheel.

The invention consists in certain other novel features of construction and ooxnoinations of parts which will be hereinafter fully described and pointed out in the claim.

In the accompanying drawings :Figure 1 is a longitudinal sectional view through my im roved hub showing the parts in their assemh ed position, Fi 2 is a View in side elevation lookin at t e outer end of the hub, and Fig. 3 IS a detail perspective view of the inner end of one of the spokes.

A bushing 1 is bored to receive the spindie 2 of an ordinary axle 3, and the bushing is further counterbored at each end to re ceive the roller bearings 4 and 5 whichnrc held in alinement by the ca s 6 and 7. The bushing 1 has a right-han screw-thread 8 :5 formed upon one end, and a left-hand thread 9 formed upon the other. -An internally screw-threaded jam nut 10 has the threads thereof'cut to fit the threads 8 on the bushing 1, and near one end has a flange 9 11 formed approximately at right angles to its central bore. A s reading-flu e 12 is formed onthe outer ace of the ange 11 around the screw-threaded bore of the jamnut 10 and'has its inner bore preferably 5 slightly larger than the bore of the screwthreaded portion. Spreading-flange 12 has its outer face 13 beveled in such a manner that it presents practically a truncatedcone, and the outer edge of this cone is preferably 9 rounded. at 14 that the flange may more readily move beneath the inner end of-the okes in assembling the several parts of t e hub. A jam-nut 15 is internally scre wthreaded to fit the screw-threads 9 of the 5 bushing, and has the flange 16 and spread- Specification a! Letter: new. Application fled larch 21, me.

taco 18, both of which are similar in every respept to those carried b the janrnut 10. An axle nut 19 is screw-threaded upon the outer end 20 of the axle spindle 2 to hold the bushing and hub u on the spindle, and

a dust-cap 21 is adapte tobe screwed upon the threads 9 on the outer end of the bushmg prevent dust from passi into the bee formed in the bushing. %16 spokes, of which-there may be any number, have the'bevel faces 22 and 23 formed near their inner ends in such a manner that when the spokes are assembled in the felly the cont guous faces at the inner ends fit together, and form a sohd structure as shown in Fig. 2.

. Theextrerne ends of the s okes are made 111 the shape of a blunt w ge by forming the two bevels 24 and 25 thereon, and these .bevels are enga d by the surfaces 13 and -18 of the sprea ing tlanges 12 and 17 carried by the two jam-nuts which force the spokes outward and seat them tightly in the felly of the wheel. As a means of preventing the jam-nuts l0 and 15 from unscrewing from the bushing 1, bolts or rivets 26 may be inserted through openings 27 formed in the two jam-nuts.

In assembling a wheel using my improved hub, the operation would be as follows The spokes would be secured in the felly of the wheel by having the tenons on their ends inserted within the o nings in the felly, or in an other suitab e manner. The bushing 2 is t en inserted through the opening at the inner ends of the spokes, and the jam-nuts 10 and 15 are screwed upon their respective ends of the bnsliing.- \Vhen the nuts 10 and '15 have been screwed a sufficient distance, the bevel faces'13 and 18 of the spreading-flanges 12 and 17 engage with the bevel ortions 2i and 25 on the inner ends of t'e spokes, and force them outward against the felly, and as the'nuts are screwed still farther u on the bushing, the spokes are engaged at tieir sides by the inner faces of the flanges Hand 16, between which they are firmly clamped and held.

It will thus be seen that I have rovided a hub by which the s okes are hel rigidly against side-wise an circumferential displacement, and with which the-outward or endward pressure is distributed over the greater area of the inner-end of the spoke.
